Awkward times ahead

Well, I have fallen out with my Mum's Husband, Neil. Or "Saint Neil" as we all refer to him. He has always been very posessive of my Mum. If she is caught so much as talking to another man he will have a tantrum and a sulk. Or if she talks about her past, he will get all queer with her. She is allowed, it seems, to talk about my father to me without irking him but everything else is strictly off limits. Anyway, since Mum has become ill he has gone into overdrive. Now I can put up with the curt, snipey comments but what I do take exception to is his attempts to stop me seeing my Mum. He shows all the classic control freak tendencies ie: tries to remove Mum from her friends (is most unpleasant to them, culminating in them ceasing to visit) and also her family (her own mother is made unwelcome). Now I have been kind and loving to this man, treated him like one of the family, in spite of my growing reservations. My Mum is a strong person, or at least always has been, and I have always been confident that she would never let a man walk all over her. Well, until now. Of course I can appreciate she is very frightened at the moment, and I don't doubt that Neil is caring for her with utmost kindness but how long will that last with a man who is not a rational human being? Circumstance are, Monday was the last time I could see Mum for a week, as she was entering her lowest period of immunity on Tuesday for a week and was trying to avoid contact with anyone unneccesary. As I am usually grubby from the horse field I accept this is sound judgement! So I arive Monday at 5pm, the back gate is locked (I always use the tradesmans) so I ring the doorbell. Saint Neil appears from the gate and wont let me past, he says bluntly "We weren't expecting you." Which is crap, as I had said on the Sunday when we went for lunch I would be coming round. I wanted to take a photo of us before she lost her hair. Anyway, I just looked at him. He told me my Mum was too tired to see me and went to walk back thru the gate! I said, "Oh, I'll just go then shall I?" to which his reply was "Good" and he walked back in and locked the gate! I was so angry and admit I was quite immature and said to him as he was locking the gate "You should stop being so over-protective, I am her daughter!" and the called him a f*$@king a-hole. Not one of my finer moments, I'll grant you, but I was incensed. I have spoken to Mum today and she is still doing fantastic. I don't intend to mention anything to her while she is undergoing treatment, he clearly hasn't said anything to her, for which I'm glad. She's on her precautionary anti-biotics and am hoping she gets through this week without catching any germs. If Saint Neil thinks he can get rid of me as easily as he has managed to eradicate some of the others then I've got news for him. Of course I have to be very tactful during these times but let's just say he's gonna get pretty sick of the sight of me over these coming months ;) The biggest shame is that if he were a normal, rational person and just accepted Mums friends and family, he could have so much fun, love and warmth. at the end of the day he's a fool to himself.
